, This invention relates to draft, dust and rain excluding devices (hereafter called weather-excluding devices) for vertically or horizontally sliding windows or doors, of the type comprising a strip-like member (hereafter called a strip) adapted to be se- I cured to the'bottoin cross rail of the window or door and having downwardly projecting flanges or parts, adapted to fit adjacent to upstanding flanges, or parts. providedon a strip secured to the sill or like member or the window or door.

According to this invention 1 provide a weather excluding device of the "type referred to, wherein one ofthe strips, which is secured to the outside of the sliding win dow ordoor, has one of its downwardly de-' pendingflanges so arranged. that, in the closed position of the window or door, said flange coversthe joint between the bottom of the window or door and the sill or like member thereof, while it also its adjacent,

' or closely, to one of the upwardly extending flanges onthe strip secured to the sill or like member, the other flange of the strip sccured to the window or door fitting between thetwo flanges of the strip on the sill or like memberand being disposed adjacent or closely to the other upstanding flange on said last mentioned strip. My weather can eluding device is thus very. efficient in action,

because the force ofthe wind is entirely spent, owing to the closely flttingfianges on the upper and lower strips at the exterior of the window or door, while, in order to penetrate into the interior of the w rdow or door, the wind has still to make its way around the flange covering the joint between the bottom of the window or door and the sill The device is easily made and can-be readily fitted to anysliding sash window or door without the necessity'oi cutting or checking the latter or the sill.

Each flange of the strip secured to the sill or like member may be formed with spaced apertures, the apertures in one flange being offset/from those in the other flange. Thus,

water driven between the two flanges may es:

capethrough the aperturesin one flange and water lodging at the back of he device may escape through the apertures in the other flangeinto the space between the two, flanges and thence out through the first mentioned apertures. The oil-setting of the two sets and in Great ,Brnamnovembere, 1525.

of apertures prevents the wind blowing straight through the device."

is illustrated, by wayof] Xample, in the an nexed drawing, whereon:-

Fig. l is a fragmentary elevation of the i lower sash of the window and the window sill, showing the device applied thereto;

' Fig. 2 is a fragmentary, elevation, to a larger scale, of the co-acting parts oat-the weather-excluding device} i Q i Fig. 3 is an end view corresponding to Fig,2;and 7 'Fig. 4 isa fragmentary elevation of the bottom part o1 the weather-excluding device.

Referring tothe drawings I I V The upper part of the device consists of a lcng metallic strip 1 which isbentover to :t'ormja vertical flange 2 and ajdownwardly depending fiange'B spaced therefrom. The

back of the fiange -2is-tormed for apart of its depth, with corrugations or ribs' l seats to effectively exclude thepassage ofdrafts, dust or rain between the joint formed by V the'back of the flaIIgeQHa-nd the lower cross rail 5 of the window. sash-5, to the. outside of which said flange is secured by means of screws 6. As will. be seen iI1i Flg. 3 ,tl16 bottom part of the flange 2 projects below the bottom of the sash 5 so as tocover the i o extending flange 9'and, at thebackend of the base, with an upwardly extending flange 10 which fits adjacent to the flange 2 of the strip 1 when the complete device is in its operative position, as illustrated in Fig. 3. In this position the lower part of the flange 9 also fits adjacent to the flange 30f the strip. In order to arrange for the removal of water which may be driven through the slight opening between the flanges 9 and 3,

a number of spaced holes 11 are formed in the flange 10 and a number of slots or recesses 12, offset from the holes 11, are also formed in the flange 9, so as to drain away any water entering the space 13 between the two flanges 10 and 9 or driven by the wind upwards from the space 13 and flowing downwards between the flanges 2 and 10.

1 In the operative position of the weather excluding device the outer face of the curved flange 3 of the member 1 is close to or in contact with'the base 7 and its outer face is adjacent to the inner face of the flange 9 of the member 1 while the outer face of the flange 10 is close up to'the inner face of the flange 2 of the member 1, as aforesaid. Thus it will be seen that, in order to pass from the outside of the window to the inside there.- of, drafts, rain, or dust havefirst to pass between the flanges 9 and 3 under the flange .3 and into the space 13 and thence down wards between the flanges 10 and 2. Itwill beobvious that by this time the force of the wind will be substantially spent and that it will be impossible for drafts. dust or rain to pass along the inside of the flange 2 and out through the aperture 16. If rain should be driven into the space 13 from between the flanges .9 and 3 it is drained away through the slots 12 in the flange 9 and any water gettingbetween the flanges 10 and 2, drains through the holes 11 into the space 13 and thence out through the slots 12. It will be seen that the flange 2 covers the-opening 16 at the bottom of the sash.

It will be obvious that improved a very efficient means for positively excluding drafts, dust or rain, from the interior of the room in whicht-he window or .door' is fitted.

\Vhat I do claim as my invention and desire to secure by Letters Patent is I 1. A weather excluding device for slidable closures, comprising a member including an inner flange and an outerflange, said member adapted to be secured to-the movable closure with the inner flange directly in contact with such closure and extending below the lower end of the closure, whereby to bridge the joint between the closure and the frame with Which it cooperates, and a second member secured to the frame and having spaced upstanding flanges, one of the flanges being arranged between the flanges of the closure-carried member and the other outward'ly beyond the flanges of the closure carried member.

2. A weather excluding device for slidable doors or windows, comprising a member in-, cluding a flange portion to be secured in contact with the door or'window'and to extend beyond that edge of the door or window ongaging the frame, said member including" an additional flange portion arranged beyond and in spaced relation to the first mentioned flange portion, and a second meinberto be secured to the frame and having spaced upstanding flanges adapted to overlie and ex tend above the lower edges of the respective flanges of the first mentioned member.

3. A weather excluding device for the joints between a sliding closure and the frame with which it cooperates, including a closure member having a flange portion to be secured to the closure and to extend beyond that edge of the closure engaging the frame, a second flange arranged outwardly beyond the closure in spaced parallel relation to the first mentioned flange, and a frame-carrying member having upstanding edge flanges adapted, when the closurev is in cooperation with the frame, to project immediately adjacent and in advance of the respective flanges of the closure-carried member, the inner flange of the frame-carried member being of greater height than the outer flange thereof.

4. A weather excluding device for the joints between a sliding. closure and the frame with which it cooperates, including a closure member having a flange portion to be secured to the closure and to extend beyond that edge of the closure engaging the frame, a second flange arranged outwardly llU beyond the closure in spaced parallel relation to the first. mentioned flange, and a frame-carrying member having upstanding edge flanges adapted, when the closure is in cooperation withthe frame,qto project immediately adjacent and in advance of the respective flanges ofthe closure-carried member, the inner flange of the closure-carried member being of a height to extend above the line of juncture between the closure and frame.

In testimony whereof I affix my signature.
